phpldapadmin crash/bug

I have a problem with phpldapadmin, it crashes my httpd. After dumping
core and gdb i get the attached backtrace. It seems to be the first
access to a ldap connection, for example (striped from lost of comments)
the following code (from lib/server_funtions.php) seems to cause the
problem.
$resource = @ldap_connect( $this->host );
@ldap_set_option( $resource, LDAP_OPT_PROTOCOL_VERSION, 3 );
@ldap_set_option( $resource, LDAP_OPT_REFERRALS, 0);
The ldap_connect goes OK since resource is not null. But the first
function that gets resource as a argument causes the sigsegv.
Before i file a bug i would like to ask if someone reproduce the
problem ?
